In the wild a public CA issued a new subordinate CA certificate
with an identical subject to another, with a new private key.
This was uninstallable using ipa-cacert-manage because it would
fail with "subject public key info mismatch" during verification
because a different certificate with the same subject but
different public key was installed.
I'm not sure of the reasoning to prevent this situation but I
see it as giving users flexibility. This may be hurtful to them
but they can always remove any affected certs.
This is backwards compatible with older releases from the client
perspective. Older servers will choke on the duplicates and
won't be able to manage these.
A new serial number option is added for displaying the list of
certificates and for use when deleting one with a duplicate subject.
ipa-cacert-manage delete on systems without this patch will
successfully remove ALL of the requested certificates. There is no
way to distinguish. At least it won't break anything and the
deleted certificates can be re-added.

Issue 8384 introduced a new installation state for the statestore
to identify when client/server installation is completely finished
rather than relying on has_files().
The problem is that ipa-client-automount may be called during
ipa-client-install and since installation is not complete at that
point the automount install was failing with "IPA client not
configured".
Add a new state, 'automount', to designate that automount installation
is in process. If check_client_configuration() fails it checks to
see if [installation] automount is True. If so it continues with the
installation.
This also addresses an issue where the filestore and statestore are
shared between the client and automount installers but the client
wasn't refreshing state after automount completed. This resulted in
an incomplete state and index file of backed-up files which caused
files to not be restored on uninstall and the state file to be
orphaned.

Also restart KRB5 KDC during ``ipa-certupdate`` so KDC picks up new CA

- The KDC must trust the CA chain of the client certificate.
- The client must be able to verify the KDC's PKINIT cert.
- The host entry must exist. This limitation may be removed in the
